J Engelsmann - Englesmann Jolting Volumeter STAV 11

• Determining the bulk density and tap density of powders and granular materials in pharmaceutical production.
• Assessing the flowability and compaction properties of food ingredients and agricultural products.
• Quality control in chemical processing to ensure consistent material characteristics.
• Research and development for new material formulations and process optimisation.
• Analysis of cosmetic powders and pigments for uniform product quality.

Typical sample volume

Commonly accommodates sample volumes ranging from 100 ml to 500 ml, depending on the specific cylinder used.

Jolting frequency

Units of this type typically operate at a fixed or adjustable jolting frequency, often around 250 strokes per minute.

Drop height

The drop height for this class of equipment is typically standardised, often around 3 mm, in accordance with industry standards.

Power supply

For laboratory equipment, a standard single-phase electrical supply (e.g., 230V, 50Hz for UK operation) is commonly required.

Footprint

These units are typically compact benchtop devices, requiring a relatively small laboratory footprint.

Measurement accuracy

Volumeters of this type are designed for high precision, typically offering repeatability within a specified percentage.

• What is the primary function of a Jolting Volumeter?

  A Jolting Volumeter, such as the Englesmann STAV 11, is used to determine the tapped density of powders and granular materials by subjecting a sample to a specified number of taps.

• How does this unit differ from a standard bulk density measurement?

• What standards can this equipment comply with?

• Is specialist installation required for this type of equipment?

• What maintenance is typically involved for a Jolting Volumeter?

Particle counters and analysis systems are regarded as essential tools for quality assurance and contamination control across pharmaceutical, biotech and food processing sectors. When purchasing used units, buyers should verify calibration history and optical component condition, as these directly affect measurement accuracy. Industry users value their reliability and precision for meeting regulatory compliance standards. Key strengths include consistent performance across batch testing and minimal maintenance requirements when properly maintained.
